To LLM whom i# may concern;

Be it known that I, BENo'r M. W. HANsoN, a citizen of Sweden, residing et Hartford, in thecounty of Hertford and State of Connecticut, have invented certain new and useful improvements in Velve-Actuating Mechsn ism, of which the following is a specification.

This invention relates to valve-actuating mechanism, and has for its object the provision of ineens for operating a valve of any suitable description and for locking said valve against movement except when re .leased at predetermined times.

A further object of the invention is the provision of e pistonjvalve, lever, and cem mechanism for actuating said piston-valve and a latch for locking and releasing the lever.

A further object of the invention is the provision, in connection with the valve, lever, and latch described, of cams for actuating the lever and for releasing the let-ch, es will he hereinafter set forth. Y Y

In the accompanying drawings, Figure l is a longitudinal vertical section of the velved easing and its supply and discharge pipes, the valve and its actuating and locking* devices being shown in elevation. Fig. 'is an end View. Fig. 3is a section showing the shoes and eanrdogs hereinafter described. 4 is e ongitudinal vertical section simii lar to the upper art of Fig. l, hut showing the valve in a di erent position.

Like numerals designate similar parte throughout the several views.

Referring to thcdrawings, the numeral l designates s section of the framework of' any desired struct-nre with which the'velve is to be employed, and the numeral 2 a guideway having an undercut Wall, said guideway rceeiving the doveteiled bese 3 ef s. veivrscas-f in? 4 and the letter being held in pince by 'e gi i 5 and bolt 6. A slotted henger 7 depends from the valve-casing 4, and in said hanger is pivoted an angle-lever 8, the hang arm of which is roiuulcd et 8' at its upper ondV and the short arm. of which is beveled et Sito form s, catcli-surface and below said surface has en extension 9, provided with en. inelisegl innereall 9 for apurposc herein l'ter stetdd'.

Journaled in the wells of thehangor is e shaft l0, carrying e, depending latch 12, 4the free end of which has s' shoulder l2, rfi/dav ted to snep over the end 8 of lever 8 end to ook seid lover in the position represented by Fig. 1. A torsion-spring 13, surrounding the shaft 10 and one erin i3 ci which hear against the honger end the other arm 13 against the hitch, serves normally lo threel the lst-tch to its locking position. (Shownin Fig. l.)

In the valve-casing 4 is a longitudinal bore, and in said here are mounted a plug l, e coiled spring i6, end aspool-shsped valve 17, the latter having a tenen I7 entering' the' spring and collars 172, e slotted collar 173, and a reduced extension i7, against which the end of lever S bears.

ln the valve-casing are :in induction-port 18, communicating with the {luid-'supply pipe 19, and. reduction-ports 20 and 21, communicating with the dischargeqiipes 22 and 23, the ls-rterheiixg hold dn chainbered nipples 24 and 25 by couplings 26.

For actuating the valve-controlling lever and its latch eny desired mechanism may he employcclfor said parts may he manually operated in seine instances, if required; but

foreeccrnplisiring the results mentioned I' have shown one form of mechanism which rney be nserhit being distinctl f understood that my invention is not limite thereto, end which mechanism will now be described. l

Designated by 27 is a carrier, shown Ves of Vvvlicei-shape, although it may he ofV other iorrn., end thiscarrier is secured to e rotary shaft 25, which may constitute an eleinent of a insehrne irrwrhioh the valve is to isc einpio'yedvfl'hs wheel is provided with e rim or'peri lery of peculiar fox-in, seid rim havingV eterni undercut extensions 272 and a concave top 29 for a purpose hereinafter described. Slices 3() and 3l, each shaped on its under side to lit the undercut extension 2?, are clamped to the {riin of the wheel-hy screws 32' and 33, respedtively, the points of Y which enter the concave recess 29, and hy i' bearing against the weil .ofthe seme Vserve adjustebly to clernp the'shocsinpiace et the desired distance e srt andlto' revent them from lateral displlscenient. eveled cam dogs 30 and 3l erecerried by the respective shoes, and thesev dogs aetnate the latch 12 and thelever 8 in a manner now to be dcscriliednn Y In nieclsinestvitl which my invention may be employed itis frequently necessary to actuete certain parte on the forward movement of the valve end other parte on the reverse movement of seid valve, and the pipes 22 and 23 are utilized to convey the motive fluidfor instenee, compressed air--to the points IXO where it is utilized. As will be evident, the spring 16 normally tends to throw the valve 17 to the position represented in Fig. 4, the latch 12 having been first tripped to permit of this action. This tripping action ol the latch is caused by the dog 30 of shoe 30, which as the wheel or carrier 27 rotates strikes the end 12 of the latch and forces 'said latch backward against the action of the io spring 13 to the position represented in said Fig. 4. In this position of the valve motive l'luid from the pipe 18 passes to the pipe 23, from which it is conveyed b v suitable connections to the point where it is utilized. i5 After the necessaryr dwell the valve is again shifted to the position illustrated in Fig; 1. and this is accomplished by the dog 31 of shoe 3l, which dog as the wheel iotates will strike. the incline of the projection 9' and aczo 'tuate the lever S to'torce the valve 17 inward against the tension ot' spring 16, as shoivn in Fig. 1, therebyl diverting the motive l'liiid to the pipe 22. When the lever is pushed inward, the shoulder 12 ot latch 12 sita )s behind the end S2 of the short arm of said lever and locks the lever until again released b v thc trip of the hitch by dog 31)', as above described. By adjusting the shoes 3U' along the rini of the wheel .27 the valve may be rc- 30 leased and locked at any desired intervals, and in this way thc llow ol' llnid either to pipe 22 or to pipe .23 may be so coiitrolhd that the proper synchronism ol: the parts actuated by said [luid may readil)v be obtained. To all'oi'd necessary ventage lor the fluid, a groove or slot 1Ta is formed in the collar 1T, as illustrated in Figs. 1 and 2, and a` port 1T is provided in casing 4.

As above stated, the invention is not re- 4o stricted to any precise form of valve, noi' is it limited to the exact devices shown and dcscribed l'or actuating said valve, t'or changes may be imide in the form, proportions, and arrangement of the parts without departure from the invention.
